Missing Child Sheet For Sheet Symbol

Modified by Phil Loughhead on Feb 20, 2014

This compiler hint appears when the link between a sheet symbol and a target schematic, OpenBus System, or HDL sub-document is invalid. This can occur when:

A sheet symbol has been placed manually but no sub-level document reference has been entered into the symbol's Filename field.
The document reference in the symbol's Filename field has been entered incorrectly - effectively targeting a document that does not exist.
The referenced target document has been removed from the project or deleted.

The message is displayed in the Messages panel in the following format:

Missing child-sheet in SymbolFileName in Symbol SymbolDesignator,

where

SymbolFileName is the current entry for the parent sheet symbol's Filename field.

SymbolDesignator is the designator of the parent sheet symbol.

Recommendation

Check the entry in the sheet symbol's Filename field. If the required target document already exists, ensure that the document name (including extension) is entered correctly into the field. If the target document has been removed from the project and you have access to it, add it back in to the project. If the target document is a schematic or HDL file and it does not exist, simply right-click on the symbol and choose one of the following commands from the Sheet Symbol Actions sub-menu - depending on the type of target document required:

Create Sheet From Symbol
Create VHDL File From Symbol
Create Verilog File From Symbol

If the target document is an OpenBus System document and it does not exist, you will need to create this document, adding it to your project.

Notes

This error is also generated when Device Sheet Symbols have been placed but the target Device Sheet cannot be found.
